Hypertension Stages

Blood pressure is the force of blood against the walls of arteries during circulation. When blood pressure stays elevate over time, then it is considering as high blood pressure, hypertension, or hypertensive.

Pre hypertension

If blood pressure is stays in between 120/80 mmHg to 139/89 mmHg, this cannot be diagnosing as hypertension and is considering as pre-hypertension. This means it is not a high blood pressure but may be likely to develop in the future. You can prevent high blood pressure by adopting a healthy lifestyle.

High blood pressure overview

Both numbers in a blood pressure test are important, but for people whom are 50 or older, systolic blood pressure gives the most accurate diagnosis of hypertension. Systolic is the top number in blood pressure reading. It is considering as high if it is 140 mmHg or above.

Globally, hypertension is a greater concern; with blood pressure causing deaths accounts for 13.5%. Majority of the hypertensive belongs to low economic status.

The prevalence of high blood pressure increases progressively with age. Results from the Framingham study show in middle-aged and elderly persons, the residual lifetime risk of developing hypertension is 90%.

Hypertension stages

Stage-1 hypertension - A mildly elevated blood pressure than normal, a BP number between 140/90 to 159/99 mmHg is considering as stage-1 hypertension. It is an early form of high blood pressure, which is considering as mild and need medical treatment with blood pressure monitoring on every doctor’s visit to avoid progression to stage-2 hypertension.

Stage-2 hypertension – A moderately elevated blood pressure, a BP number between 160/100 to 179/109 mmHg is considering as stage-2 hypertension. It is second stage of hypertension, which is considering as moderate and need immediate medical treatment with frequent monitoring to avoid its progression to stage-3 hypertension.

Stage-3 hypertension – A severely elevated blood pressure, a BP number over 180/110 mmHg is considering as stage-3 hypertension. It is the third stage of hypertension, which is considering as severe and need urgent stringent medical treatment with more frequent monitoring to avoid any hypertension complication.

Resistant Hypertension

A patient is considering having resistant hypertension when his or her blood pressure is not controllable despite treatment with an optimal dose of three antihypertensive drugs of different classes with one of the agents being a diuretic.

Isolated systolic hypertension

Isolated systolic hypertension is an elevation in only the systolic number of your blood pressure (the top number). Diastolic number (the bottom number) remains normal or slightly elevated.

Stage-1 isolated systolic hypertension - A mildly elevated systolic BP number between 140 to 159 mmHg, but the diastolic BP number stay lower than 90 mmHg is considering as stage-1 isolated systolic hypertension. This needs medical treatment with blood pressure monitoring on every doctor’s visit to avoid its progression to stage-2.

Stage-2 isolated systolic hypertension - A moderately elevated systolic BP number over 160 mmHg, but the diastolic BP number stay lower than 90 mmHg is considering as stage-2 isolated systolic hypertension. This needs immediate medical treatment with frequent blood pressure monitoring to avoid hypertension complications.
